FASTENER.

Specification of Letters Patent.

Patented Aug. 8, 1916.

To all whom it may concern:

Be it known that I, JACOB P. HoL'rz- HOUSER, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

This invention relates to fasteners for windows, doors, box covers, etc., and is designed to provide in addition to the fastening means, means for starting the opening of the moving member.

In the drawings-Figure 1 is a front view of a complete fastener. Fig. 2 is a side view from the right of Fig. 1. Fig. 3 is a side view from the left of Fig. 1. Fig. 4, a front edge view of the cam member looking from the bottom of Fig. 1. Fig. 5, a front edge view of the keeper looking from the top of Fig. 1.

Referring to the drawings, 0, denotes the cam member, and b the keeper. The cam member comprises a base 2, a double faced cam 3 pivoted thereon as at 4 and provided with an operating handle 5.

6 is the closing cam, with its low part 7 at the front and inclining upwardly to the rear.

8 is the opening member, with its high part 9 at the front and inclining clownwardly to the rear.

The keeper 7) has an upstanding projecting lip 20, preferably but not necessarily inclined laterally at an angle to its base to provide a wedging surface both top and bottom with which the cams 6 and 8 cooperate.

I have spoken of the cam 6 as a closing cam, and the cam 8 as the opening cam, under the assumption that the cam member is attached to the moving part. Obviously, if the cam member be attached to the stationary part, 6 would be the opening cam and S the closing cam.

The operation of the device will be apparent, and it will be seen that it provides means for both fastening and locking a part, and also for starting the opening of the part locked, if it should be stuck in place.

The device is preferably made of sheet metal though it may be made otherwise, and it is subject to other modifications without departing from the spirit of the invention as set forth in the appended claim.

I claim as my invention A fastener comprising a base member, a stud carried thereby, a cam member having a flat central body-portion flatly resting on the base member and having a central opening for receiving the stud, the stud engaging the upper face of the cam member for holding the same in position, the said cam member being substantially semi-circular in plan view with a substantially straight front edge, a horizontal inclined wall carried by the flat central body-portion of the cam and.

having the high and low edges terminating at the straight front side, a handle carried by the rear edge of the inclined wall, a

.lreeper having a raised central portion, and

an inclined forwardly projecting lip adapted to be engaged by said cam.
